Apostolepis is a speciose Neotropical snake genus, encompassing approximately 40 species, widely distributed at South America. Most species of the genus are known based on small series, which has contributed to a convoluted taxonomic history. In this study, we report the rediscovery of Apostolepis niceforoi, a taxon that remained known from a single specimen since 1935, providing a detailed redescription, with comments on its close congeners, as well as taxonomic misidentifications related to this species.
